Thank you very much!
I was almost there and couldn't understand why the text of the query was still being saved in the text file, until I read that the SET options are only good if you use it in a sql script (separate file) and then source to in the bash script, like so:
File query.sql:
Code:
SET ECHO OFF
SET VERIFY OFF
SET FEEDBACK OFF
SET PAGESIZE 0
SPOOL myfile.txt
SELECT field1, field2 FROM mytable;
SPOOL OFF
exit

Then in the bash script:
Code:
#!/bin/bash
sql @query sql

It worked like a charm!

RESET(7)							   SQL Commands 							  RESET(7)

NAME

       RESET - restore the value of a run-time parameter to a default value

SYNOPSIS

       RESET variable

       RESET ALL

   INPUTS
       variable
	      The name of a run-time parameter. See SET [set(7)] for a list.

DESCRIPTION

       RESET restores run-time parameters to their default values. Refer to SET [set(7)] for details. RESET is an alternate spelling for

       SET variable TO DEFAULT

       The  default value is defined as the value that the variable would have had, had no SET ever been issued for it in the current session. The
       actual source of this value might be a compiled-in default, the postmaster's configuration file or command-line switches,  or  per-database
       or per-user default settings. See the Administrator's Guide for details.

       See the SET manual page for details on the transaction behavior of RESET.

DIAGNOSTICS

       See under the SET [set(7)] command.

EXAMPLES

       Set DateStyle to its default value:

       RESET DateStyle;

       Set geqo to its default value:

       RESET GEQO;

COMPATIBILITY

       RESET is a PostgreSQL extension.
